SAFETY-PIN.

SPECIFICATION forming part of Letters Patent No. 770,304, datedSeptember 20, 1904.

Application filed March 4, 1903.

To all whom it may concern:

Be it known that I, HENRY A. NORTON, a citizen of the United States,residing at VVashington, in the District of Columbia, have invented newand useful Improvements in Safety-Pins, of which the following is aspecification.

This invention relates to safety-pins; and the purpose of the same is toprovide a novel form of shield for the pin and to dispense with coils togive the said pin a spring action, thereby economizing the cost ofmanufacture of the device as an entirety and at the same time producinga strong and durable device of this class.

The invention consists in the construction and arrangement of theseveral parts, which will be more fully hereinafter described andclaimed.

In the drawings, Figure 1 is a side elevation of a device embodying thefeatures of the invention and showing the pin open in clotted lines.Fig. 2 is a bottom plan View of the device. Fig. 3 is a side elevationof a slightlymodified form. of the device.

Similar numerals of reference are employed to indicate correspondingparts in the several views.

In the present form of pin the usual springcoil is dispensed with andreplaced by a single bend 1 between the back bar 2 and pin 3, theextremity of the back bar opposite that continuing from the bend 1 beingformed with a bend t. The bend t is merged into or attached to ashield,which differs in construction in the several forms of pins. Thepin 3 is given a resilient or spring action to cause it to fly outwardlywhen released from the shield by an inward bend 5 adjacent to the bend1, this bend 5 being common to all forms shown, and in addition the pinshown by Fig. 3 has a supplementary bend 6 opposite the bend 5 and asimilar bend 7 adjacent to the bend 4, thus giving the bends 1 and 4: asubstantial circular contour. The bend 5, however, is the most essentialfeature of construction relative to the spring control and operation ofthe pin 3 and replaces the usual form Serial No. 146,149. (No model.)

of coil and renders the pin effective in an automatic outthrow ormovement when released and also a tight engagement between the point ofthe bar 3 and the shield when said bar is closed.

The improved form of shield consists of an elongated spiral 8, which iscontinuous with the wire forming the bend L and opens or has theterminal thereof disposed in such position that the point of the bar 8may be readily engaged therewith or withdrawn therefrom in theoperations of closing and opening the pin. In detaching the pin from theelongated open spiral 8 said pin is drawn longitudinally and sprunglaterally, and in securing this pin to the spiral shield a reverseoperation ensues, or the pin is-first pushed laterally in one directionagainst the spiral and then in an opposite direction to set up aconnection between the pin and shield which will resist accidentaldisengagement.

It will be understood that the body of the pin will be constructed ofspring-wire of suitable gage and tempered sufficiently to preventbending or misshaping the parts 2 and 3 by use.

The improved pin in its different forms is applied as ordinary devicesof this class, and it will be seen that the elongated spiral shield 8will firmly hold the point of the pin against accidentaldisengagement,and in all the forms of the device shown as soon as the pin is releasedit will be thrown outwardly away from the shield through the use of thebend 5.

Less material is required to make the improved device, owing to theabsence of the usual spring-coil, and time and labor are saved insecuring the ordinary sheet-metal shield in place by continuing thewireinto an elongated spiral to provide a shield 8.

It is proposed to ornament the device by plating the same, and suchmetal will be used in constructing the device as is best adapted for thepurpose.

Having thus fully described the invention, what is claimed as new is Asafety-pin having a back bar shaped at its opposite terminals to formsingle bends, from when pressure is applied to the pin and one of thesaid bends being continued into a body members.
